Dear teacher, you are leaving again. I want to tell you that you have worked hard. The silkworms in spring will weave until they die, and the candles will drain the wick every night.

It takes three generations to make a gentleman. You watered the flowery land with hard sweat. Teacher, don't worry, we will become the pillars of the country.

Dear child, six years of good times have become the past in a blink of an eye. One day, I will ride the wind and waves, raise the sails covered with dark clouds and cross the deep sea. We will meet again in 10 years and recall our childhood together.

Please forgive me.
